Acquisition: At the date of acquisition the Corporation records the assets and liabilities of acquired companies on the Consolidated Balance Sheet at their fair value. The results of operations for acquired companies are included in the Corporation's Consolidated Statements of Income beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the Consolidated Statements of Income during the periods incurred.

Recently Issued Accounting Pronouncements Not Yet Effective: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016 - 13, Financial Instruments—Credit Losses (Topic 326 ): Measurement of Credit Losses on Financial Instruments. This ASU adds a new Topic 326 to the codification and removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities. Under current U.S. generally accepted accounting principles, companies generally recognize credit losses when it is probable that the loss has been incurred. The revised guidance will remove all current loss recognition thresholds and will require companies to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that the corporation expects to collect over the instrument's contractual life. ASU 2016 - 13 also amends the credit loss measurement guidance for available-for-sale debt securities and beneficial interests in securitized financial assets. The guidance in ASU 2016 - 13 is effective for “public business entities,” as defined in the guidance, that are SEC filers for fiscal years and for interim periods within those fiscal years beginning after December 15, 2019. Early adoption of the guidance is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. However, during July 2019, FASB unanimously voted for a proposal to delay this ASU to January 2023 for smaller reporting companies. On October 16, 2019, FASB approved a final ASU delaying the effective date. The new guidance is effective for annual and interim periods beginning after December 15, 2022 for certain entities, including smaller reporting companies. The Corporation is a smaller reporting company.
